My sixline goes to work on my vermetid snails and is a bristle worm boss!Just wanted to share some success I've had with eradicating vermetid snails. I have a 2 tanks, a 40 AIO and a 20 AIO. The 40 is over a year old and the 20 is fairly new. I've always had the occasional vermetid snail in the 40 but they never spread and always just disappeared when one would pop up. I never thought anything of it until I set up my 20 gallon. I used some rock from my 40 to help with the cycle. After about a month the new tank was infested with vermetid snails. It kinda clicked that the snails never took off in my 40 gallon because I have a sixline in it. So I added a yellow banded possum wrasse to my 20. 2 weeks later, snails are gone. This may be common knowledge, but I wanted to share my success, incase someone is battling these pests in their tank.
